IMPROVED EGG-BEATER.

Specification forming part of Letters Patent No. 412,603, dated May 3, 1864.

To all whom it may concern:

Be it known that we, VILLIAM SALLADE and E. M. LUCKETT, of the city of Philadelphia, in the State of Pennsylvania, have in-l vented a new and useful Improvement in Egg- Beaters; and we do hereby declare that the following is a full, clear, and eXact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a plan view of the upper end or top, and Fig. 2 a vertical central section, of the apparatus, showing our Iimprovement ap plied, like letters indicating the same parts when in both gures.

The object of our invention is to facilitate the introduction of the beaters into and their withdrawal from the containingvessel of a rotary egg-beater without impairing the gen- 'eral adaptation of the latter for the purpose.

It consists, substantially as hereinafter described and specified, in the application of guide pieces or grooves opposite to each other on the inner side of the containing-vessel, for receiving, guiding, and steadyin g the opposite ends of a bar or bars connecting the lower ends of the shafts of the beaters, the. said beaters being suspended from a corresponding bar or bars fixed on the cover of the said vessel.

In the drawings, A is the containing'- vessel, a' being its cover, and a2 the bar fixed on the latter; B B, thcrotary beaters; D, the bar which connects the lower ends ofthe beaters, and a4 a4 the grooves or guide-pieces for the said bar.

The containing-vessel A in the present instance is cylindrical in form, and made of tinplate. Its upper end is fitted with a removable cover, a', and across its upper surface a metallic bar, a2, is fixed, which, together with the cover a', supports the shafts B B, together with the pinions b2 b2, spur-wheel C, crankhandle c', and another corresponding metallic bar, D, attached to the lower ends of the shafts. (See Fig. 2.) The journals of the upperends ofthe shafts B are each providedwith suitable shoulders, b3, to bear against the under side ofthe cover al', while the bosses of the pinions b2, which are txed on the shafts, bear, respectively, upon the upper side of the bar a?, and at the same time allow the shafts to have a free rotary motion. rlhe spur-wheel C is about four times larger than the pinions b2, and is made to be rotated by means of the hand-crank C upon a boss, a3, which is fixed in the middle of the bar a2, and thus to produce the required rotary motions of the sevaral `shafts B. 'lhe shafts B B are kept parallel with each other, when introduced into the vessel A, by means of the secondary bar D, through which their lower ends pass loosely as journals, the bar D being retained thereon by riveting the ends of the said ljournals.

0n the inner side of the vessel A two grooved guide-pieces, a4 a4, are fixed diametrically opposite to each other, so as to receive the respective ends of the bar D in applying the cover, and retain the same in a steady position parallel with the upper bar, a2, after the cover has been adjusted to the vessel, as seen in Fig. 2, and thus keep the beatingshafts always in a steady and proper position in use. The arms b are in this instance bent into the form of an F in their horizontal planes, and are xed in their respective shafts so as to pass, during the rotary motions of the shafts, in opposite directions without contact either with each other or with the opposite shaft.

It will be readily seen that by giving rotary motion to the center wheel, U, the beatingshafts -B B will each be rotated with, say, four times greater velocity, and that, although each shaft will rotate in the same direction, the inner ends of their respective arms will be moved in directions contrary to each other, and so as to effect a most thorough agitation and intimate mixing of the semi-duid contents of the vessel. It will also be seen that great facility is afforded by the mode of applying' the beater-shafts to the vessel, for withdrawing and replacing the same in cleansing and using, that the beaters will always be kept in their proper vertical positions in the vessel, and that the whole apparatus is very substaniial and simple in its construction, and not liable to get out of order.

Although the drawings represent only two beater-shafts, B B, it is not our intention to limit them to that number, but to apply either two, four, or more when the special service of the apparatus required to be made m-ay render an increased number necessary or expedient. The faint lines y indicate the intended positions of the stay-bars, guides, and pinions D, in combination with the boaters B B, bar a2, and cover (if, the whole being constructed and arranged to operate together substantially in the manner described, for the purpose specified.
